Dave,
I can't read others minds, but in essence I think your friends want you to get help. Have you considered any face to face support outside of SR? For me, this helps a lot being around others with a common problem and helps with feelings of loneliness.
Perhaps it's time to consider some additional support??
You're friend surely care about you, but actions and not words or intentions garners support from others many times. Maybe they have to see some change.....??!?
Glad you're here with us
